Gate Drivers ICs

UCC27323D Description

The UCC27323D from Texas Instruments is a high-performance, dual-channel, low-side gate driver IC designed for robust power MOSFET and IGBT switching applications. Housed in an 8-SOIC package, this surface-mount device operates over a 4.5V to 15V supply range, delivering 4A peak source/sink current for fast switching transitions. With 20ns rise and 15ns fall times (typical), it ensures minimal switching losses, making it ideal for high-frequency applications. The inverting input logic (VIL = 1V, VIH = 2V) simplifies interfacing with control circuits. Its independent channels allow flexible configuration for driving multiple switches.

UCC27323D Features

• High Current Drive: 4A peak output current (source/sink) enables rapid gate charging/discharging, reducing switching losses.
• Fast Switching: Ultra-low propagation delays (20ns rise, 15ns fall) optimize efficiency in high-frequency designs.
• Wide Supply Range: 4.5V–15V compatibility supports diverse system voltages.
• Independent Channels: Dual inverting inputs for isolated control of two power switches.
• Robust Packaging: 8-SOIC with MSL 1 (unlimited) rating ensures reliability in harsh environments.
• Compliance: ROHS3 and REACH unaffected, meeting environmental standards.

UCC27323D Applications

• Motor Drives: Efficiently controls MOSFET/IGBT gates in BLDC and stepper motor systems.
• Switch-Mode Power Supplies (SMPS): Enhances performance in buck/boost converters and inverters.
• Solar Inverters: Optimizes power switching in renewable energy systems.
• Industrial Automation: Drives high-current loads in PLCs and robotic controls.
• LED Drivers: Ensures precise switching for high-brightness LED arrays.

Conclusion of UCC27323D

The UCC27323D stands out for its high-speed switching, dual-channel flexibility, and robust current drive, making it a superior choice for power electronics demanding efficiency and reliability. Its wide voltage range and compliance with environmental standards further solidify its suitability for industrial, automotive, and renewable energy applications. While marked as Last Time Buy, its performance remains unmatched for legacy or new designs requiring proven gate-drive solutions.
